Mining Pools

note: Most miners mine via mining pools, which aggregate hash power to reduce variance in mining returns. While individual miners may also express a preference for or against a fork, pools serve as a proxy for the sentiment amongst their constituent miners, were they to misjudge they might lose hashrate.

Mining percentages were estimated as of October 7th, 2021 from recent data.
